WIRE-COVERING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 512,146, dated Jannary 2, 1894. Application filed June 7, 1393. Serial No. 478,869. (No modeL) To all whom it may concern:

Be it known that I, WALT R HERBERT Avis, a subject of the Queen of Great Britain, residing at Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in WVire-Oovering Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to design a simple, effective and quickly operating machine for covering wire or other cords with insulating material, and it consists of mechanism, substantially as hereinafter described and more particularly claimed.

Figure 1 is a side elevation partly in section of my improved machine; Fig. 2, a bottom plan view on line a: or; of Fig. 1; Fig. 3,

a sectional transverse view in elevation on the same line. Fig. 4, is an enlarged sectional detail of the dish used to contain the insulating material and its connections; and Fig. 5, a plan view of same with the cover removed; Fig. 6, a detail in elevation'of flier and immediate connections.

A is a hollow spindle made in three parts,

a, a, a carried vertically in suitable bear-- not confine myself to any special number, but find that about six bobbins will be the proper number.

On reference to Fig. 4, the'special construc tion of the dish D, will be understood. It is composed preferably of a single piece of light metahand has a central sleeve K, by: wh ch 111 lssecured by means of a set screw K ,to the revolving spindle. D, is a detach able cover on which are mounted brackets D carryln g pulleys I. The dish is also provided Two arms and two bObblllS are shown in the drawings, but I do with tubes H, running through the same toward said pulleys. There are holes 0, in the cover through which the yarn is admitted, all 5 5 as presently described. Inside the dish. is provided with lower brackets D to carry pulleys J, and upper brackets D each to carry a roller L, and aspring M. Each piece of yarn G, is carried through a tube II, in the dish, then around .a pulley 1, down through the insulating material and around a pulley J, placed in the bottom of the dish D, thence upwardly between projections 0 on the sleeve K, and squeezing roller L, which is elasticallyheld by the spring M, on bracket D and squeezes out any surplus insulating compound which may adhere to the yarn. The insulating yarn is then carried up through holes 0, in the cover and against guide rollers m through grooves h, in the surface of the conical top N, to its upper point, which directs the yarn to the Wire 0, on which it is laid as the machine revolves. The wire or core is carried upward from a reel Y, at the bottom of the machine. By passing the yarn G, through the insulating material while the yarn is loose, the said yarn is morethoronghly impregnated with the insulating material than it would be if the yarn were carried through it after being twisted or wound upon the wire, and in this way I socure a more thoroughly insulated wire than is possible in any other process with which I am familiar. 4

In order to keep the prepared starch or other insulating material contained in the dish D, in proper condition to penetrate the yarn I keep it hot, as desired, by providing a gas jet P, held close to the dish D, as indi- 9o cated. Instead of the gas jet P, a coil of steam pipe or other means for applying the heat to the dish may be adopted. 1 In the drawings I have shown an arrangement of two dishes having similar parts and connections. The dish D, is provided with a bracket D carrying at its top a ring friction roller D and which has a beveled face. The roller D, engages withverticalbeveled edged frictional rollers F, mounted on-a horizontal I00 axis 11, and the rollers F, engage with a horizontal friction disk T, mounted on part a, of spindle A.

The object of duplicating the dishes and their operating and connecting parts is to apply to the wire 0, an additional layer of insulating yarn. The arrangement is shown in Fig. 1. The upper dish D is placed on the part a of the spindle, and the two dishes are run in reverse directions so that the yarn wound upon the wire by the lower device shall be closed by the yarn applied by the upper device. In. this arrangement the upper disk T, carries the fliers as and for the purpose hereinafter explained, and the fliers are revolved in a direction opposite to that of the dish D below them.

The spindle A, is provided with a cap joint Q, made substantially as shown in Fig. 4, coupling the parts of the spindle a, a, 0. and allowing them to work independently of each other. This cap Q, is shaped as shown to fit over the conical top N. It is placed over the top N, and forms a step on which the bellshaped end R of each of the spindle parts rests. The end It is secured by a screw 7 to the spindle. This cap Q, effectually protects the top N, from oil and dirt and not only constitutes a suitable step to support a portion of the spindle A, but also aids to keep the spindle in line above the dish D.

With the view of giving a handsome finish to the insulating covered wire, I provide the following device for twisting and laying in one operation an outer coating of yarn or similar material, which may be of various colors. To accomplish this, I connect to the upper spindle pa'rt a frictional disks T, T and arrange a series of fliers U,journaled in rollers Z, carried by the said disks. Only two fliers are shown in the drawings, but at least four should be employed and as many more as desired be used. A slot 1: is made in the disk T, through which the spindle V, of the flier U, is inserted. In the bottom of each slot and at right angles to the spindle another slot if, is made into which the plunger W, is placed,a spring X, being placed behind each plunger. On the end of each plunger a fork is made, the said fork constituting a bearing into which the spindle V, is fitted. On this spindle V, I fix a friction roller Z a are rings fixed to the frame B.

The revolving of the part a of spindle A, causes the disks T, T to revolve, and as all the fliers U, are carried in slots made in the disks the centrifugal force produced by the rotary movement will throw all the fliers outwardly forcing the friction rollers, Z against the rings a thereby imparting a rotary movement to each of the fliers U. The tension of the springs X, is arranged to force the rollers Z againstthe rings a thereby insuring the revolving of the fliers immediately upon the disk T, revolving.

Z2, is abobbin spindle pivoted at d, to the spindle V, its bottom fitting into a recess or hole made in the-top of the step e, which step is supported by a spring f, fitted into the bearing spindle g, fixed to the center of the lower friction roller Z, corresponding with the upper friction roller Z The step e, being elastically supported by the springf, it may be moved down so as to permitthe end of the bobbin s'pindleb, to be pressed into place or removed as required. For that purpose I provide a light spindle 2', provided with abut- ,ton j, so that by pulling upon the button the step 6, may be pushed down clear of the the bobbin may be taken off, or a fresh one put on.

With the view of increasing or decreasing the tension of the springf, I provide an adjustable nut 75, which may be moved for that purpose.

on spiders a, suitably journaled as indicated in Fig. 6. These spiders are held by frictional contact so that they will. revolve with the spindle V, but not sufficiently to prevent them revolving on their own axes shouldit be necessary to preventthe breaking of the yarn p, which is carried around the rods an, arranged as shown' for the purpose of imparting the necessary friction of the said yarn. 'It will be observed on reference to Figs. 1 and 6, that the yarn p, is carried from the bobbin around the rods m, thence through the loop q, up to the spiral groove r, inthe spindle V, to the central hole in the said spindle, thence over the pulley S, to the center of the hollow spindle A, where it is wound upon the wire 0. By carrying the yarn 19, through the center of the spindle V, which is revolving, the yarn is twisted before it reaches the wire 0, and when every flier is supplied with a different colored yarn, the twisted yarns thus applied impart a very handsome finished appearance to the covered wire 0'. By carrying the yarn 19, through the spiral groove 1', located at the bottom of the hole through the spindle V, I insure that the twisting of the yarn 19, shall be completed at the commence- Ementefthe spiral groove r, which is a very important factorin the manipulation of the yarn. By the time the wire 0, has reached the top of the frame B, the covering of the said wire is completed, first, with yarn thoroughly impregnated with a suitable insulating compound soaked through in an untwisted condiondly, by twisted yarns preferably of contrasting colors which impart to the covered wire a handsome finished appearance. The flier and bobbin arrangement above described is not claimed herein.

In order to draw the wire 0, through the covering mechanism described, and Wind the fective machinery:

The covered wire 0, extends from the top of the idle pulley t, over rollertiwhich directs it to a. clutching deviee,.consisting of a disk a, fixed to the shaft '0, which is caused to revolve from some convenient driving mechanism,

tion before it is applied to the wire, and see-'- same on bobbins ready for commercial purposes, I provide the following simple and efspindle b, to permit it to be movedout so that A series of vertical rodsm, is arranged around the bobbin spindle b, and IS earned and over a series of fingers w, on disk to,

, equally as serviceable for laying the coveron bobbins being each directed through a hole thence over pulley 10 then down around pulley w thence up over a removable reel 3, journaled in a drum 4.

It will of course be understood tliatinstead of using my machine for covering wire with insulating material, theupper portion of the machine which is used for laying the twisted yarn on the covered wire, will be found a core of any other kind of material.
